This is a callback routine supplied to UNDI at undi_start time.
UNDI call this routine with a virtual or CPU address that SNP provided to
convert it to a physical or device address. Since EFI uses the identical
mapping, this routine returns the physical address same as the virtual address
for most of the addresses. an address above 4GB cannot generally be used as a
device address, it needs to be mapped to a lower physical address. This
routine does not call the map routine itself, but it assumes that the mapping
was done at the time of providing the address to UNDI. This routine just
looks up the address in a map table (which is the v2p structure chain).
